Delta Membrane Systems Limited were chosen as waterproofing consultancy to the design team for the Harley Gallery extension. The new Harley Gallery was opened in March 2016 to house the Portland Collection which includes Masterpieces such as Michelangelo’s Madonna del Silenzio.
Delta Membrane Systems Limited took care of the project from design stage to completion on site. The main contractor was Caddick Construction of Knottingley in West Yorkshire and our Delta Registered installer was Preserva CSS of Derby. Delta Membrane Systems were involved in all design consultations, product certifications, reviews, design team meetings, site meetings and delivered a successful product which exceeded expectations.
The main gallery slab is recessed below external ground level and it also houses all the environmental controls and plant machinery that is required to maintain the stringent climatic conditions required to protect the priceless works of art. This is protected by two coats of Delta Koster Deuxan 2c polymer modified bitumen mesh reinforced and applied over smooth concrete blinding, protected by Delta GeoDrain Quattro drainage and protection membrane, which is flashed in and buried just below external ground level, using a Delta MS Profile Capping Strip.
Caddick Construction and Hugh Broughton Architects were delighted with Delta Membrane System Limited's services, their onsite attendance, assistance and knowledge.
